[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. This technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobiles, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.

[0003] For 3D printers that use plastic as the bonding material, after the product is printed, the temperature of the product is too high and the natural cooling time is too slow. The product cannot be removed from the platform and the next product cannot be printed without being completely cooled. This will reduce the printing efficiency of the 3D printer.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers.

[0029] In the related art, for 3D printers that use plastic as the bonding material, after the product is printed, the temperature of the product is too high and the natural cooling time is too slow. The product cannot be removed from the platform and the next product cannot be printed without being completely cooled. This reduces the printing efficiency of the 3D printer, so a fan is set on the platform for auxiliary blowing to achieve the purpose of rapid cooling and molding.

[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a 3D printing rapid prototyping device. When it is needed, it is only necessary to rotate the rod body 121 to move the mounting plate 13 to the top of the product, and then rotate the screw 111 to limit and fix the rod body 121, and then adjust the position of the connecting plate 19 according to the diameter of the product. After the adjustment is completed, the fixation is completed by turning the screw 2 171. After all adjustments are completed, the motor 14 is started so that the worm 141 drives the worm gear 16 to rotate, thereby driving the transmission rod 15 and the frame 17 at the bottom thereof to rotate. The rotation of the frame 17 can drive two groups of fans 191 installed on one side of the connecting plate 19 to rotate, so that the two groups of fans 191 will blow air around the product to achieve the effect of quickly cooling and molding the product, and avoid the situation where the fan 191 is inconvenient to move, which affects the efficiency of product cooling and molding.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figure 1-Figure 3The embodiment of the present application provides a 3D printing rapid prototyping device, comprising a cooling molding component 1; a support platform 11, the top of which is rotatably connected to a turntable 12; a screw 111 is arranged on the support platform 11 and inserted into the inner side of the support platform 11; a 3D molding mechanism 112 is arranged on the support platform 11; a rod body 121 is arranged on the top of the turntable 12; a mounting plate 13 is arranged on the top of the rod body 121; a motor 14 is arranged on the top of the mounting plate 13; a worm 141 is arranged on the The output shaft of the motor 14; the transmission rod 15 is arranged on the top of the mounting plate 13 and passes through the mounting plate 13; the worm wheel 16 is arranged on the outer wall of the transmission rod 15 and meshes with the worm 141; the frame 17 is arranged at the bottom of the transmission rod 15; the plug 18 is sleeved on the inner side of the frame 17; the screw 171 is arranged on the frame 17 and is threadedly connected with the frame 17; the connecting plate 19 is arranged on the plug 18; the fan 191 is symmetrically arranged on the connecting plate 19.

[0033] After the product is printed by the nozzle inside the 3D printing mechanism, the rod body 121 is rotated. Since the turntable 12 at the bottom of the rod body 121 is rotatably connected to the support platform 11, the mounting plate 13 can be rotated to the top of the product. Since the screw 111 is threadedly connected to the support platform 11, the screw 111 is rotated to screw it into the inside of the support platform 11, and the turntable 12 is squeezed and fixed. The length of the plug block 18 is adjusted according to the diameter of the product to prevent the fan 191 on the connecting plate 19 at one end of the plug block 18 from contacting the product. After the adjustment is completed, the screw 2 171 is rotated to insert it into the inner side of the frame 17, and the plug block 18 is squeezed and fixed. After the adjustment is completed, the motor 14 and the fan 191 are started by an external power supply or a battery. The fan 191 will blow air to dissipate heat for the product. 14 will drive the worm 141 to rotate, the worm 141 drives the worm wheel 16 meshing with it to rotate, and the worm wheel 16 drives the transmission rod 15 rotatably connected to the mounting plate 13 to rotate, thereby achieving the effect of driving the frame 17 to rotate. In this way, by starting the motor 14, the fan 191 can be driven to rotate around the product, so as to achieve the effect of quickly cooling and molding the product, and avoid the situation where the fan 191 is inconvenient to move, which affects the efficiency of product molding. After the product is cooled, the screw 111 is rotated to contact the turntable 12, and the entire mechanism is rotated to the other side to avoid affecting the next batch of 3D printed products. The principle of the 3D printing mechanism 112 is the same as the comparative patent "CN202211333334.1 A platform adsorption mechanism for a 3D printer".

[0034] In some embodiments, an auxiliary component 2 is disposed on the mounting plate 13 , and the auxiliary component 2 includes a protective shell 21 disposed on the top of the mounting plate 13 .

[0035] A protective shell 21 is provided on the top of the mounting plate 13, and the worm wheel 16 and the worm 141 are covered by the protective shell 21 to protect them from being exposed to the outside, and at the same time, parts are prevented from being exposed to the outside, thereby increasing the aesthetics of the device.

[0036] In some embodiments, the auxiliary component 2 further includes a scale 22 disposed on the plug block 18 .

[0037] A scale 22 is provided on the front side of the insert block 18, so that the length of the insert block 18 can be adjusted in advance according to the diameter of the product, so as to avoid collision with the product during rotation, resulting in damage to the product and affecting the quality of the product.

[0038] In some embodiments, the insert block 18 is connected to the connecting plate 19 by bolts.

[0039] The plug block 18 and the connecting plate 19 are configured to be bolted together, so that the fan 191 can be disassembled for cleaning or replacement later, thereby preventing dust from adhering to the surface of the fan 191 and blowing it onto the product, affecting the quality of the product, or the fan 191 can be damaged and replaced in time.

[0040] In some embodiments, the auxiliary component 2 further includes a slot 23 opened on the connecting plate 19 .

[0041] A slot 23 is provided on one side of the connecting plate 19 , so that when the connecting plate 19 is installed, the inserting block 18 can be inserted into the inner side of the slot 23 , so that the connecting plate 19 can be quickly connected to facilitate fixed installation.

[0042] In some embodiments, the insert block 18 is rectangular in shape.

[0043] The shape of the plug block 18 is set to be a rectangle, so that when the plug block 18 is docked with the slot 23, the connecting plate 19 can be prevented from tilting and affecting the use of the device. When the rectangular plug block 18 moves inside the frame 17, the plug block 18 can be prevented from rotating, causing the connecting plate 19 to rotate, thereby increasing the structural stability of the device.

[0044] In some embodiments, the rod body 121 is an electric push rod.

[0045] The rod body 121 is set as an electric push rod, so that the height of the frame body 17 can be adjusted according to the height of the product to avoid contact with the product and damage to the product. The electric push rod is powered by an electric motor, and the rotation of the motor is converted into a linear motion of the push rod along the guide rail through gear reduction or a worm gear driving a lead screw nut, and the forward and reverse rotation of the motor is used to realize the reciprocating forward and backward motion of the push rod. The corresponding principle structure is not drawn in the attached figure in this section.

[0046] In some embodiments, the protective shell 21 is connected to the mounting plate 13 by bolts.

[0047] The protective shell 21 and the mounting plate 13 are connected by bolts, so that it is convenient to dismantle the protective shell 21 later and maintain the worm wheel 16 and the worm 141 inside.
